CSS collision with jQueryUI

Version 6.3 uses certain CSS classes which have the same name as classes in jQueryUI. There's no problem until there's a plugin (in our case, Structure), which use jQueryUI and integration with GreenHopper.

The integration requires us to include certain web resources on the Agile board page, including jQueryUI. This results in unexpected greying out of the whole Sprint sections, which was immediately noticed by the customers and reported as a bug — see attached screenshot.

To reproduce:
1. Install the latest version of GreenHopper and Structure
2. Create a Scrum board, and a Sprint on it

Since iQueryUI is a pretty standard library which can be used by other plugins as well, I would suggest namespacing JIRA Agile CSS in some way to avoid the collision.

Thanks!
